In my blog I mentioned that the next app update was due for "early November". Testing has since uncovered some important improvements that were needed, which we've added. The extra delay plus the app store review times now mean the blog schedule is offset by up to a couple of weeks, so the app update is set for some time in the second half of November instead.
Some other elements of the timeline which were due for late December may potentially be delayed in to January as well, such as better wheel-to-wheel racing in 3D, if we are not able to finish it before Christmas.
It's only a minor discrepancy on the timeline but worth mentioning early to avoid any confusion, since we're already aware of it.
